Cool. I guess I'll quit locking doors, leave valuable items
unsecured and unattended in plain sight, and generally rely on
law enforcement to keep everything safe. It'll be more
convenient and less effort for me.

ISPs cannot block 100% of Internet nastiness. By no stretch of
the imagination does this mean ISPs shouldn't try, but users need
to take on some responsibility, too.
